GCSContentsManager throws up a popup saying `Directory Not Found`

[jayasimha-raghavan-unskript]

I am trying to use Google Object Store with Jupyterlab and S3Contents[gcs] package. I see that the Notebook gets loaded and I am able to Read/Write to the Object store. However, when I open the Notebook I see this popup

How do i disable this popup?

In a codeblock in the README there is an example on how to fix this popup:

# Fix JupyterLab dialog issues
c.ServerApp.root_dir = ""

For my environment, this fix did not work, since my kernels would not load if I used this config. I had to change it to:

# Fix JupyterLab dialog issues
c.ServerApp.root_dir = "/"
